of Austria, residing at 'Neunkirchen, Lower Austria, Empire of Austria-I-Iungary, have invented certain new anduseful Improvements in Machines for the Manufacture of Pasteboard Boxes, (for which Letters Patent have been granted in the following countries: Austria, No. iii/4,533, dated November 11, 1896; Hungary, No. 6,490, dated March 5, 1896; Belgium, No. 120,188, dated March 6, 1896; France, No. 254,531, dated March 5, 1896; Great Britain, No. 4,987, dated March 5, 1896 5 Norway, No. 5,013, dated March 23, 1896; Switzerland, No. 11,935, dated March 5, 1896, and Turkey, No. 492, dated March 21, 1896;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for making pasteboard boxes, and particularlyto that class of machines designed for the making of boxes of rectangular form open at one end and formed from a blank consisting of a rectangular bottom piece with wings projecting therefrom which form the sides and end of the box.

My invention consists of the several parts constructed and arranged as will be hereinafter fully described and claimed.

A designates the mold, which is formed of four blocks A, mounted upon the frame X, projecting upward from the base X of the machine. The blocks A are mounted to slide slightly toward and away from the center of the mold. At the center of the mold the frame X is perforated to receive the spindle 20, having the disk 20' at its end within the mold, which disk is countersunk to lie flush with the bottom of the mold, and the said spindle extends through the said frame X and is supported at its outer end in the bearing X secured to the base X of the machine. This spindle is adapted to slide longitudinally in its bearings and is actuated at the proper times by the lever a, pivoted on the support X and extending into the cam-groove w in the cylinder N, mounted upon the drivingshaft V, which latter extends longitudinally through the machine and is supported in suitable bearings in blocks X at the ends of the base X, and the said driving-shaft is adapted to receive motion from any suitable source of power.

Two pairs of curved levers 1414 are pivoted in the frame X and have adj usting-screws 14 in their short arms which bear upon the ends of the blocks A. The long arms of the levers 14 are curved, so as to approach the spindle 20, and have rollers j ournaled in their ends which rest upon the cone-shaped portion of the sleeve 14?, mounted to slide upon the spindle 20 and actuated by the lever a, fulcrumed on the support X and extending into the groove 20 in the cylinder \V upon the driving-shaft W, which groove is so formed as to move the sleeve 14 to force the mold-blocks A together at proper times. Springs (6*, connected to lugs on the mold-blocks A and to any suitable place on the frame X, serve to pull the mold-blocks apart when the sleeve 14: is moved in the opposite direction.

On the face of each block A slides a fiat piece D, the inner edges of whichare normally flush with the inner edges of the moldblocks A. These sliding pieces are held in their normal position by bellorank levers d, fulcrumed at d and extending through slots in the blocks A. The two horizontal bellcrank levers d have one arm connected with the sliding sleeve (1 mounted on the spindle 20, to cause the two levers to move simultaneously, and one of these levers is provided with a third arm 6 which extends into the cam-groove 10 in the cylinder TV on the driving-shaft WV.

The two bell-crank levers d for operating the vertical slides D are connected with arms D (shown in dotted lines in Fig. 1,) which extend from the sleeve d mounted to slide upon the spindle 20, and the said sleeve 01 is operated by a lever dflwhich extends into the cam-groove 20 in the cylinder WV on the driving-shaft \V. The arrangement of the camgrooves 1.0 and 10 is such as to cause the pieces D to approach each other and return to their normal positions in pairs acting alternately. This movement of the sliding pieces D is for the purpose of folding the edges of the adhesive strip down upon the bottom of the box, as will be hereinafter explained.

In recesses in the inner corners of the sliding pieces D are pivoted the folding-arms d which have short arms (Z projecting therefrom and forming an acute angle with the arms 61. To the short arms d are pivoted rods diwhich extend into slots d in the facepieces A and have caps or disks (Z attached to their upper ends. Coiled springs (Z are placed around the ends of the rods d to press against the disks 61 While theblocks D are in their normal positions, the armed rest against the faces of the mold-blocks A,while the short arms d" lie close to the sides of the said mold-blocks, as shown in Fig. 23. The purpose of these arms d is to fold the edges of the adhesive strip down inside of the edges of the box. This is accomplished when the pieces D descend below the edges of the moldblocks A, when the tendency of the spring 61 is to pull up on the short arms 61 and turn the arms d into a horizontal position below the mold-blocks A", as shown in Fig. 24. Should the box be in the mold, these arms 61 would turn inside of the said box and fold the edge of the adhesive strip down, as will be hereinafter explained.

The frame P is mounted on trunnions P supported in bearings X and carries in suit able bearings two spindles b and 0, respectively. The spindle b is normally in line with ICO IEO

The frame P is supported in its normal p sition upon the vertical rod 29 arranged to slide in suitable bearings in the frame of the machine and pivoted to the end of one arm of the bent lever 19 the opposite end of which lever extends into the path of the cam p on the driving-shaft YV and has an antifrictionroller mounted in its end to roll upon said cam. The action of the said cam 19 upon the bent lever 13 rocks the frame P on its trunnions and brings one or the other of the dies B O in front of the mold A, as shown in solid and dotted lines in Fig. 5. The die-spindles b and c are mounted to slide longitudinally in the frame P, and the spindle b is capable of being rotated in its bearings also. The flanged sleeve 12 is rigidly secured to the spindle b and has the sleeve b rotatably mounted thereon, to which latter sleeve is pivoted the end of the lever l), fulcrumed upon the central piece 1? of the frame P and extending into the cam-groove in the cylinder W on the driving-shaft W. This camgroove 10 is of such a shape that it will actuate the lever I) to slide the die-spindle 1) toward the mold A and cause the die B to enter the said mold at the proper times, as will be hereinafter explaincd.

On the end of the die-spindle 1), near the die B, is mounted the ring E, having the hub E, which encircles the said spindle b, but is free to slide thereon. The die-spindle h is hollow and has a second hollow spindle or tube E arranged therein and extending nearly the entire length thereof, and to this inner spindle E is secured the hub of the ring E by means of the screws e", which extend through slots Z1 in the die-spindle b, as shown in Fig. 6. The flanged sleeve 5 is arranged to slide upon the spindle Z) and is connected by screws with the inner spindle E, which screws extend through slots Z9 in the die-spindle l9, thus allowing the sleeve 9 and spindle E to slide together and carry the ring E without moving the die-spindle b.

The ring E is provided with four radial arms E which are perforated longitudinally to receive rods e, the axial lines of the said perforations and rods being parallel with diagonals drawn on the face of the die B. Each of the rods e is provided at its outer end with two pins 6, which extend over the corners of the box, as shown in Fig. 10, in which the dotted lines indicate the relative position of the box on the die.

The flanged sleeve b is provided with the sleeve 5 to which is attached one end of the lever e fulcrumed on the cross-piece P of the frame P", the other end of the said lever 6 extending into the cam-groove in the cylinder WV; which cam-groove is formed so as to move the said lever at the proper times to slide the ring E toward or away from the die B. Between the ring E and the die B is mounted the ring 15,'having both edges beveled and free to slide on the said spindle for a distance limited by the stops Z2 and b and when the ring E is moved toward the die B the inner ends of the rods 6 will push the ring 15 along the spindle until it strikes the stop I), when they will ride up the beveled edge of said ring, which'will cause the said rods to slide outwardly, carrying the pins e beyond the corners of said die B. As the ring E continues to approach the die B the pins e will pass over the corners of the said die, and when the rods 6 ride down the other inclined edge of the ring 15 the action of suitable springs (shown at e will cause the pins 6 to fall upon the sides of thedie,on each side of the corners thereof, as shown in Fig. 10.

The rod b extends entirely through the diespindle b and inner spindle E and carries on its end a disk N, which is countersunk in the face of the die B and normally remains flush therewith, as shown in Fig. 6; but when it is desirable to remove the box from the die the said rod 19 and disk 5 may be moved outwardly with relation to the die, as shown in Fig. 11. This relative movement of the die and disk is caused as follows: The slot 11 is formed through the die-spindle l) and the inner spindle E, and the annular groove Z7 is formed in the rod 19 within the limit-s of the slot Z9 The lever 18 is pivoted in the frame P of the machine in such a position that one end will enter the slot Z1 and the annular groove 19 in the rod b The other end of the lever 18 extends to the periphery of the cylinder W which latter is provided with a rib partly encircling the same and which holds the end of the lever 18 out of the groove Z1 until the die B is about to leave the box in the mold, when the lower end of the lever 18 will pass'off of the rib on the cylinder Vi and allowthe upper end of said lever to fall into the groove 72 in the rod 11 and thus as the die-spindle and die are moved backward the rod 12 will be held from movement, causing the disk 5 to hold the box in the mold until the die and the gripping-pins e are withdrawn therefrom. After the die has been withdrawn from the box the lower end of the lever l8 will again ride upon the rib on the cylinder W and raise the said lever out of the groove 19 when the rod 12 and disk I) may be moved back by any suitable means-as, for instance, by the lever 1), extended beyond the sleeve 5 on the spindle l), as at b and in position to strike a stud 18 on a sliding bar Z), arranged to slide in a suitable guide-slot p in the frame P. At the opposite end of the sliding bar I) is a similar stud 18, arranged to strike a lever Z), which lever is pivoted to the frame F at one end and fastened to a sleeve 11 on the spindle b at its other end. This sleeve 19 is frame P.

die-spindle b and the inner spindle E and also through a short slot in the rod N. Then the lever b in moving the die-spindle back nears the end of its stroke, its end I) will impinge against the stud 18 on the sliding bar 11 and move the latter also. The stud 18, acting on the lever 12 near its fulcrum-point, will cause its opposite end to move the-sleeve b rapidly backward, thus drawing the rod 19 and disk 19 back to their normal positions "within the die-spindle and die. It is obvious that in smaller machines this mechanism for moving the rod and disk back may be dispensed with and a spring used in place thereof,.which will accomplish the same result.

A keyway b is formed in one side of the spindle Z), and a ratchet-wheel F having a key F to slide in the said keyway, is mounted to slide on the said spindle and to rotate therewith. A disk F is rotatably mounted on the said spindle close to the ratchet F and the said disk and ratchet are held close together and in the same relative position to the frame of the machine between the bearings P and P on the frame P. Thus the spindle is free to slide through the ratchet F and disk 1?. A pawl f is pivoted on one side of the disk F to engage the teeth on the said ratchet, and on the other side of the said disk is secured a pinion f having teeth which mesh with a rack f arranged to slide in the Motion is imparted to the rack f by the lever f fulcrumed to the cross-piece P of the frame P and so bent that one end will extend into a slot in the rack f while the other end will extend into the cam-groove w in the cylinder W'. The cam-groove w is so shaped that the rack will move far enough to cause the spindle b to make one revolution as the rack moves in one direction; but as the rack moves back the pawl f will slip over the teeth on the ratchet F so that the spindle will not be turned.

To prevent the spindle b from being turned accidentally, a disk 17 is secured thereon, and a long pawl 17 X is arranged to engage a notch in the said disk 17 and so hold the shaft from rotation. The pawl l7 is made long enough to remain in engagement with the notch through the entire sliding movement of the spindle Z). This pawl 17 X is securedto a pair of levers 17, pivoted to the frame P and having an extension 17, provided with a roller 17", reaching to the cylinder W which is provided with any suitable meansas, for instance, a cam 10 (see Fig. 35)for tripping the said levers and throwing the pawl 17 X out of the notch in the disk 17 to allow the spindle I) to begin its revolution, after which it will drop back against the periphery of the disk 17 until the revolution is completed, when the pawl l7 will fall in the notch in the disk 17 and hold the spindle b from rotation, as before. The collar f is mounted to slide upon the spindle b and has pivoted thereto the curved arm f carrying at its outer end the plate F, adapted to be brought in contact with the side of the box on the die, for a purpose to be hereinafter explained.

The arm f is provided, just back of its f ulcrum-point, with a lip f, and a second ring F is also arranged to slide on the spindle b and is provided with a beveled edge f which is adapted to pass beneath the lip f and thus force the arm f down until the plate F presses against the side of the box on the die 13. The ring F is provided with an annulus f, and the lever f notched at its end to engage the said annulus, is fulcrumed to the frame P and connected with a second lever f by the link f This second lever f is fulcrumed upon the cross-piece P of the frame P and extends in the path of the cam 10 on the cylinder W, which will act upon said levers to move the ring F toward the ring f and beneath the lip f to cause the arm f to descend upon the side of the box at the proper time, for a purpose to be hereinafter explained. The forward movement of the ring f is limited by the stops f and the said ring is connected with the ring F by slotted links f which will permit the ring F tov move far enough away from the ring f to withdraw the beveled edge 7 from beneath the lip f of the armf after which the ring f will be drawn after the ring F in its backward movement, as will be readily understood by reference to Fig. 36 of the drawings.

The die 0 is carried on the end of the spindle c, mounted to slide in suitable hearings in the frame P, and the sliding movement is imparted thereto by a lever 0 (shown in dotted lines in Figs. 1, 3, and 4,) which is fulcrumed to the frame P and extends into the cam-groove L08 in the cylinder W, which groove is so formed as to cause the die 0 to move into the box in the mold and to withdraw the said box from the mold when finished. Two strips 19 19 are secured to the face of the frame P, one on each side of the die 0, and serve the double purpose of keeping the said die and spindle c from turning in their bearings and to strip the finished box from the said die as the latter nears the end of its backward movement.

Pivoted on a suitable support or bracket 0; on the base X is the lever h which carries at its upper end the table or jaw 11, over which a strip of paper or other suitable material H, having an adhesive substance spread over its lower side, is arranged to move. A second lever 72, having the fiat jaw h at its upper end, is-supported on the same pivot 00 with the lever 71 but is provided with a slot h through which the pivot extends, thus allowing the lever h to move vertically as well as about its pivot. The lever its is provided at its upper end with a guide-piece 71, extending longitudinally from the end thereof, and which guide-piece extends through the jaw M on the lever 71, thus causingthe two levers to move together above their pivot 03 but allowing the lever h to slide longitudinally on the lever 77;. The lever h is somewhat longer than. the lever 7L and extends below it, as at 7L8, for a purpose to be hereinafter explained. The shaft h is j ourn aled in suitable bearings on the base X and has at one end the arm k actuated by the cam v on the shaft W, and at its other end an arm h to which is pivoted the lever 71, one end of which is adjustably connected with'the lower end k of the lever 7L, as at h and the other end 72, is extended into the path of the cam V on the drivingshaft W, all as shown in Figs. 12 to 14. By inspection of the said figures it will be seen that when the end of the lever 72, passes off the cam N it will allow the lever h to fall, which action is assisted by the spring 7%, which tends to pull the lever h downwardly and which will press the flat jaw 71 down upon the table H or upon the adhesive strip H upon the said table, and themovement of the arm 7L2, caused by the cam W will cause the arm 79 to move the lever h and cause the jaws on the upper ends of the two levers 7t and 71 to approach the box on. the die B until the end of the adhesive strip is placed on one side of the said box, as shown in Fig. 13, after which the cam will act on the end h of the lever h to raise the lever h and release the said adhesive strip from between the jaws H and h".

Vhen the adhesive strip has been wound once around the box, it is out off by the cutting device K,which consists of an upper and lower frame K and K respectively, pivoted together at 150 and supported in the frame I. The frames K and K are provided with knives or cutting edges and 79 respectively. The frame K is provided with an extension k to the end of which is pivoted a rod is, connected at its other end to an arm 7ton the shaft K having at its other end the arm 16 Fig. 2, extending into the path of a cam on the shaft W'. The lower frame K is connected by the rod 76 with the same arm 76, so that when the said arm moves downwardly the rod 70 will move the lower frame downwardly, and the rod k, pulling on the extension kiwill move the frame K upwardly and thus open the knives or cutting edges 70 and it. hen the arm 7a is moved upwardly, the movements are reversed and the knives are brought together. The adhesive-strip H is arranged to pass through the frame I, where it is held from backward movement by retaining-pawls 1, through the frames K and K and between the knives k and is, where it is cut 0% at the proper times.

The pasteboard blanks may be fed to the machine in any suitable manner; but I prefer to use a plain strip of pasteboard, which is fed to the machine between guides 1 1 and between the vertical guides 3, in which are pivoted clieclopawls 3, which prevent backward movement of the strip, and the said strip is caught by the reciprocating frame 2,

havin the awl 3 which enga es the said i strip of pasteboard at its lower edge. The frame 2, as shown in Fig. 34, is a three-sided frame arranged to slide on the guides 1 1 and 1, the upper and lower ends thereof being connected together by a bolt or rod 2 which carries at its lower end, just over the lower guide 1, the pawl 3 and near its middle theblock 2 To the block 2 is pivoted the eye 2 of the eyebolt 2, which eyebolt is free to slide in a slot in the upper end of the lever 12. A reciprocating motion is imparted to the frame 2 by means of the lever 12, fulcrumed to the base X of the machine at x and having its upper end connected with the said frame 2 at 2 andits lower end adj ustably connected at 12 with a link 13, connected to one arm of the ,lever as, the other arm of which lever extends into the path of a cam on the shaft W, so placed as to impart to the said lever 03 and the parts connected therewith a reciprocating motion. The bolt 2 is free to turn in the ends of the frame 2. From inspection of Figs. 1, 3, and 34 it will be seen that when the lever 12 moves the frame forward it will pull upon the eyebolt 2", thus turning the rod 2* in the direction to cause the pawl 23* to press against the strip of the pasteboard and move the same forward, and when the lever 12 moves backward it will turn the said bolt 2 in the direction to cause the pawl 8 to turn away from the pasteboard, which latter will be held from backward movement by the pawl 3. The frame 2 moves the pasteboard strip along to the cutting device G by a step-by-step movement, where it is cut to the shape shown in Fig. 18. This cutter G consists of two punches 4 l, one at the top and one at the bottom, and a knife 6, extending from one of the said punches to the other. The two punches and the knife are arranged to be pressed into two spaces 5 5 and the groove 6 in the piece of metal G, secured to the frame of the machine in the proper position to receive them, as shown in Figs. 1, 15, 16, and 17. The cutter G, carrying the said punches and knife, is arranged to slide in the piece G secured to the frame of the machine, and the said cutter is provided with a tailpiece g, which extends near the periphery of the cylinder W and has journaled to its end the roller g, which extends into the cam-groove w on the said cylinder WV, and thus reciprocates the cutter at the proper times. The blank after being cut is pushed forward by the pawl S, pivoted on a block 8', mounted to slide on the lower guide 1, and pivoted at its other end to the end of the rod 9, which is arranged to slide in suitable bearin gs in the frame of the machine and is provided at its other end with the rack 9 The toothed segment 9 is pivoted to the frame of the machine in such a position as to mesh with the teeth on the rack 9 and the said segment is provided with theeating movement of the lever 12 will be'imparted to the rod 9 and pawl 8 through the segment 9 and rack 9 The pivotal motion of the pawl 8 on the block 8 is limited by a stop 8", so that as the rod 9 moves forward the pawl S will strike the said stop 8 when the said pawl has turned far enough to press against the pasteboard blank, and the further movement of the rod will slide the block along the guide 1, carrying the pasteboard blank with it. WVhen the rod 9' moves backward, it will pull upon the pawl 8 in the direction to turn its end away from the pasteboard blank and drag the block 8 backward along the said guide 1. The pawl 10 is pivoted on the bent end of the rod 11, which is arranged to slide in the frame of the machine and is connected to the lever 12 at 12 and is reciprocated thereby. The purpose of the pawl 10 is to move the pasteboard blank in front of the mold in position to be forced into the mold by the die B.

The operation of the invention is as follows: The pasteboard band of the required width is fed into the machine by any suitable means and enters in an upright position into the guide 1, Figs. 1 to 3, in which it receives a step-by-step forward motion bymeans of feed devices consisting of a pawl 3 carried by the reciprocating frame 2, which pawl is made to press against the pasteboard during the forward motion, but slide over the same at the backward motion of frame 2, during which the bandis prevented from receding by a counter-pawl 3, pivoted to one of the vertical guides 3. The pasteboard band brought in this-manner in front of the cutting device G 'is-cut off by the knife 6 and punches 4 4 in the shape indicated in Fig. 18, each out cutting the rear end of one blank and the front end of thenext blank, thus forming a finished blank at each cut. The blank is then pushed forward by the pawl 8, which is operated by the rack 9 and segment 9, until it is caught by the pushing-pawl 10, which at the next movement pushes the blank in front of the mold A in position to be acted upon by the die B. The cam-groove. w, which actuates the lever b, is so formed that it will move the die ]3 into the mold as soon as the blank is in the proper position in front of said mold. As the die moves into the mold the central rectangular portion S of the blank will be carried to the bottom of the mold and the sides or wings s will be bent down upon the sides of the die in the form of the finished box. As soon as the die has reached the bottom of the mold the cam-groove w will act on the lever a to move the sleeve 14 and through the levers 1 L move the mold-blocks toward-the center of the mold, thus pressing the wings s of the blank closely against the sides of the die 13. WVhile the wings are in this position the cam-groove 20 will act on the lever e to move the gripping device E toward the die B. As the rods e ride over the ring 15 the pins 0 will be forced outwardly and pass over the sides of the box on each side of the corners, as shown in Fig. 10, the pins 6 entering the recesses e in the sliding pieces D and mold-blocks-A'. When the rods 6 have passed the ring 15, the springs 6 will cause the pins 6 to press upon the sides of the box and so hold the said sides or wings close down upon the die B. The camgroove 10 will at this time move the lever b in the direction to move the die out of the mold, bringing with it the blank S, which is held on the said die in the form of a box. At the time the die begins to move out of the mold the lever to and sleeve 143 will be moved in the direction to loosen the mold-blocks A and the spindle 20 will be moved forward by the lever ct, acted upon by the cam-groove w, and will follow the movement of the die B, thus pushing the box out of the mold with the said die, after which the said spindle 20 is moved back to its normal position. As soon as the die B has moved out of the mold the levers h h and 71 71. will be acted upon by their respective cams and will first move the lever h downwardly to bring the plate h down upon the adhesive strip H upon the table II and then to move the upper ends of the levers h and k toward the box on the die B until the end of the adhesive strip is brought against the side of the box. While these movements are taking place, the cam '10 is acting upon the lever f to move the rings f and f toward the die 13, and these movements are so timed that when the adhesive strip H touches the side of the box the lever f will bring the plate F down upon the end of the said adhesive strip and hold the same against the box. As soon as the plate F- has taken hold of the end of the adhesive strip the lever 71. will be moved upwardly to release the adhesive strip, and then both the levers h and 77, will be returned to their normal position by their respective cams on the shaft W', the adhesive strip being held from backward movement by the pawl i in the frame I. At this time the lever f is acted upon by the cam-groove w to move the rack f 7 and cause the spindle b and die B to make one complete revolution. WVhen the die has made about three-quarters of its revolution, the lever f is returned by a cam, similar to the cam 10 in the proper position upon the cylinder WV, which movement will withdraw the arm f and plateF in time to prevent the adhesive strip from being placed over it. The roller L is journaled in the arm 16, mounted on the shaft L, and the said roller is pressed against the adhesive strip by means of a spring Z, (see Fig. 2,) secured to the shaft L, while the said adhesive strip is being wound on the box, and serves to roll the said adhesive strip smoothly upon the box. The toe Zis also secured to the shaft L and extendsin the path of the lever Z, arranged to be acted upon by a cam on the shaft W to move the said roller away from the box at the proper time. As the levers h and 71.5 move away from thebox the lever k is ICO IIO

moved by its cam to raise the rods Zr, and close the blades it M, which will cutthe adhesive strip oif. As soon as the spindle b and die B have made one complete revolution they will stop and the pawl l7 will drop into the notch in the disk 17 and thus hold the said spindle from further rotation, and as the rack f is returned to its original position the ratchet-teeth on the disk F will slip beneath the pawl f without rotating the said spindle. As soon as the die stops the roller L is moved away from the box, and the die-spindle and die are once more moved toward the mold; but the cam-groove w is so shaped that this time the die will stop with the bottom of the box flush with the faces of the sliding pieces D on the mold-blocks A and the edge of the adhesive strip, which is somewhat wider than the box and projects on each side thereof, ex-

tending inside of the mold. While in this p0 sition the two vertical sliding pieces D are moved toward the center of the mold by means of the lever 11 and the cam-groove 10 the other pair of sliding pieces remaining stationary and acting as guides for the moving pair. This will fold the edges along the upper and lower sides of the box down upon the bottom thereof, and as soon as this is accomplished the vertical pair of sliding pieces D return to their normal position and the horizontal pair of sliding pieces D are similarly moved by the levers cl and 6 3X and the cam-groove 10 to fold the edges of the strip at the end of the box down upon the bottom thereof It is obvious that'either the vertical or horizontal pair of sliding pieces D may be set to move first, as may be desirable. When these sliding pieces have folded the bottom edges of the strip down upon the bottom of the box, the die-spindle and die, with the box therein, will be moved into the mold and the die-spindle and die will be immediately withdrawn; but this time the pawl 18* will be released by its cam on the cylinder 7 and will drop through the slot 71 into the annular groove Z in the rod b and as the die and spindle move out of the mold the rod 12 will be held from movement and the disk b will hold the box in the mold, the die 13 and the grippingpins e being drawn out therefrom, and the die spindle and the several parts carried thereby will all be moved back to their ini tial positions as soon as the die is clear of the box. The box is in the mold with its edges flush with the faces of the mold-blocks A and the edges of the covering-strip extending into the path of the sliding pieces D, which latter are now moved in pairs, as before, toward the center of the mold; but in this instance they first fold the edges of the covering-strip down at right angles to the sides of the box and then the levers (I operate to fold the paper down inside of the box, as will be readily understood by reference to Figs. 25 and 26. The cam p on the shaft N is arranged to act on the lever 19 just as the le-. vers (1* complete their work of folding the edges of the covering-strip down within the box, and the said lever 19 will raise the rod 19 and rock the frame P upward upon its trunnions, thus bringing the die 0 to the place formerly occupied by the die 13. When the die 0 is in the proper position and the sliding pieces D have resumed their normal places, the cam-groove 10 will act on the lever c and move the diespindlc' c and the die 0- into the box in the mold A and immediately withdraw the same, the spindle 20 being again moved forward, following the die C- and pushing the finished box from the mold. As the die C nears the frame P and passes between the strips 19 thereon the said strips will push the finished box from the die 0, allowing it to fall into any suitable receptacle. As soon as the finished box is delivered from the machine the frame P and the parts connected thereto will be returned to their normal positions by the cam-grooves in the several cylinders on the driving-shaft W and the same' operations will be repeated in the formation of another box.

In Fig. 29 I have shown a modification of themechanism for raising the die 0 in front of the die B. In this instance the vertically sliding frame P takes the place of the rocking-frame P and is moved vertically by the lever 13, operated by the cam 19 on the second driving-shaft W journaled on the other side of the machine.

In Figs. 30 to 33 I show still another device for accomplishing the same result, in which both the rocking and sliding frames are dispensed with and the second die 0 is supported in the frame 0 the sides of which are provided with slots 0 through which the pivotpins 0 pass. The said pivot-pins c are secured to the frame of the machine in such a position as to support the die G below the die B. A pair of rods 0 are pivoted to the frames 0 at c and are arranged to be moved forward at the proper times by suitable cams on the shaft W. The forward movement of the rods 0 will first swing the die O in front of the die B and then move it forward into the box in the mold A, and the backward movement of the said rod will draw the die G and the box out of the mold A. A pair of hellcrank levers c are pivoted on hangers 0 depending from the rods 0 one arm of the said bell-crank lever extending forward by the side of the die 0 and the other arm thereof extending upwardly by the side of the rods 0 in the path of the stud c projecting from the frame of the machine. Springs 0 are arranged to hold the horizontal arms of the bell-cranklever c upwardly above the sides of the box on the die C, but as the rods move backwardly the vertical arms of the said bell-crank levers will strike the stops 0 causing the other arms thereof to move down the side of the die G and remove the box therefrom I If desired, a label may be pasted on the finished box while it is still on the die 0, any

suitable means being employed for this purpose.

With the above-described machine boxes of different sizes can be made by changing the mold and dies or by fixing on or removing cheeks fixed by means of screws with countersunk heads. The last-named means are employed if boxes of a very small depth are to be made. The stroke of the dies is in this case varied either by shifting the actuatinglevers or by changing the corresponding cams and the feed of the pasteboardland the forward motion of the guide-table II for the covering-strip is also suitably modified.

It will be obvious that the above-described machine can be modified in various ways with out departing from the nature of the said invention, and I therefore do not limit myself to the exact details of construction as described. Thus the second plunger or die 0 may be dispensed with and the first die B may be caused to enter the finished box in the mold A after the front edges of the covering-strip have been turned inward and pressed onto the sides of the box forthe purpose of drawing the box out from the mold A. It is only necessary for this purpose to suitably shape the cam-groove actuating the spindle b of the die B. The box would then be moved from the die B by pushing forward the spindle b with the head 12 no separate stripping-0E plates, such as 19, or stripping-levers, such as c, being then necessary. The mechanism for actuatin g the spindle b for this purpose may be the same as that already described for pushing the said spindle forward for the purpose of retaining the box in the mold A at the first withdrawal of the die B from such box. It is, however, preferred to use the second die 0 in those cases when a label has to be pasted onto the finished boxes or an inscription printed upon them before they leave the machine.
